The CEO of Time's Up resigned last week after a sexual assault claim was made against her son, the organization said Friday.

Lisa Borders, who became the CEO and president of Time's Up in November 2018 after previously serving as president of the Women's National Basketball Association, announced Monday she had resigned "with deep regret" in order to "address family concerns." She did not provide further details at the time.

On Friday, though, Time's Up said that Borders had informed members last week that her son had been accused of sexual assault, and she decided to resign within 24 hours. "We agreed that it was the right decision for all parties involved," the statement adds. This followed a report from the Los Angeles Times on the allegations.

Borders was the first CEO and president of Time's Up, which formed in 2018 as a movement against sexual harassment and assault. The group says Chief Operating Officer Rebecca Goldman will serve as interim CEO "while we conduct an executive search." Brendan Morrow
